We investigate the properties and phase behavior of the water–diesel fuel–Neonol AF 9-6/2-ethylhexanol system, which is regarded as a promising microemulsion fuel. A pseudoternary diagram of the system has been obtained. In the diesel fuel/water (DF/W) ratio ranging from 98:2 to 50:50 and the emulsifier concentration of 8–40 vol %, a region of microemulsions has been distinguished, generating particular interest as an alternative fuel. In the region under study, a reverse micellar phase L₂ has existed predominantly. Fish-cut diagrams have been obtained for the DF/W ratios in the emulsifier concentration–temperature coordinates. An increase in the water fraction in microemulsions significantly has narrowed the range of their stability. The critical changes of microemulsion properties have been identified using the fish-cut diagrams. We have established the empirical relationship among the phase inversion temperature, the emulsifier concentration in the phase inversion point, and the water fraction in microemulsions.

非离子表面活性剂与脂肪醇结合稳定的柴油中水包油微乳液燃料的性质和相行为

我们研究了水-柴油燃料-Neonol AF 9-6 / 2-乙基己醇系统的性质和相行为，该系统被认为是有前途的微乳液燃料。已获得系统的伪三元图。在柴油/水（DF / W）比为98：2至50:50且乳化剂浓度为8–40 vol％的情况下，微乳液区域得到了区分，引起了人们对替代燃料的特别关注。在研究区域中，胶束反向相L ₂主要存在。在乳化剂浓度-温度坐标中获得了DF / W比的鱼肉切割图。微乳液中水含量的增加显着缩小了其稳定性范围。使用鱼肉切割图可以确定微乳液性能的关键变化。我们已经建立了相转化温度，相转化点中乳化剂浓度和微乳液中水份之间的经验关系。
